Mexico's government says it plans to use dolphins trained by the US Navy to try to save the world's most endangered marine species, the vaquita porpoise.
Environment Minister Rafael Pacchiano said that the dolphins would be deployed to locate and herd vaquitas into a marine refuge. Mexico also permanently banned fishing nets blamed for the vaquitas' decline.
Scientists estimate that fewer than 40 of the mammals are still alive in their habitat, in the Gulf of California.
The Mexican government also said on Friday it was imposing a permanent ban on gillnets, which are blamed for trapping and killing the porpoises. Hollywood actor Leonardo DiCaprio, who has campaigned to save the vaquitas, tweeted that the ban was "great news", thanking President Enrique Pena Nieto and environmental group WWF.
